Conventionally, as an example of this type of damper, as shown in FIG. 3, an annular space 1b is formed in a hub 1 having a pulley groove 1a formed on the outer peripheral surface, and a first damper section 2 is configured within the space 1b. In addition, a double mass type torsional damper is known in which a second damper portion 6 is configured on the outside of the hub 1 so as to be aligned with the hub 1 in the axial direction. The first damper section 2 has a vibration ring 3 and a sleeve 4 arranged in the radial direction, and an elastic body 5 made of rubber material is vulcanized and bonded between the two members.
The parts are integrated into the annular space 1b. The second damper section 6 is constructed by arranging a vibration ring 7 and a plate 8 in the axial direction, vulcanizing and adhering an elastic body 9 made of rubber between the two members, and extending the plate 8 as shown in the figure to form a hub 1. A bolt 10 is fixed to a flange 1c integrally formed on the inner periphery of the flange 1c.

In the conventional torsional damper described above, the plate 8 is extended to attach the second damper part 6 to the hub 1, and the extended part is bent to match the shape of the hub 1. 8 has become larger in size as a whole, and its shape has become more complicated, resulting in a problem in that it takes more time to manufacture and leads to higher costs. In addition, in order to fix this plate 8 to the flange 1c with bolts 10, a mounting space is required on the inner periphery of the hub 1 body, and if this space cannot be taken for some reason due to the design, a second damper with this configuration is required. There is a problem that the part 6 cannot be attached to the hub 1.

In view of the above points, the present invention does not require the use of a large and complicated plate as described above, and also allows the hub and vibration ring to be placed side by side in the axial direction even when installation space cannot be secured on the inner circumference of the hub. In order to achieve this purpose, in a torsional damper in which a hub and a vibration ring are aligned in the axial direction, an elastic body is attached to one end of the vibration ring in the axial direction. Attach a plate, form a penetration part into which a bolt is inserted between the vibration ring and the elastic body, bolt the plate to the hub, and position the head of the bolt only within the penetration part of the elastic body in this fastened state. The structure is as follows.

In other words, the damper of the present invention connects and fixes the plate and hub by inserting bolts through the through holes formed in the vibrating ring and the elastic body.Since the mounting position of the bolts has been changed to be closer to the outer diameter, the radial length of the plate can be reduced. can be shortened to eliminate the extension part and eliminate the need for the mounting space. In addition, in the fastened state, the head of the bolt is located only within the penetrating part of the elastic body, and the head and the vibration ring are shifted in the axial direction, so that even if the vibration ring swings widely in the rotational direction during operation, it will not be affected. The vibration ring does not come into contact with the bolt head.

ことができる。 In FIGS. 1 and 2, a vibration ring 7 and a flat plate 8 constituting the second damper section 6 are shown.
are arranged in the axial direction, and an elastic body 9 made of a rubber material is vulcanized and bonded between the two members. The vibration ring 7 and the elastic body 9 are formed with a required number of circular hole-shaped penetration portions 7a, 9a arranged at equal intervals through which the bolts 10 are inserted.
A bolt 10 inserted into holes 8a and 9a is screwed into a female screw hole 1d of the hub 1 through a through hole 8a of the plate 8. The penetrating portions 7a and 9a include a portion 7a drilled in the vibration ring 7 and a portion 9 drilled in the elastic body 9.
a are arranged in the axial direction, and in the state after fastening, the head 10a of the bolt 10 is positioned only within the penetrating portion 9a of the elastic body 9 as shown. The plate 8 has its inner and outer diameters adjusted to the same size as the main body of the hub 1, and is firmly fixed to the hub 1 with bolts 10. Inside the hub 1, there is a first
A damper section 2 is provided. In the torsional damper having the above configuration, the mounting position of the bolt 10 is changed to be closer to the outer diameter than in the conventional technology, so that the radial length of the plate 8 can be shortened, the plate 8 can be made smaller, and its shape can be simplified. It is also possible to assemble the hub 1 even when there is no mounting space on the inner periphery of the hub 1. Further, in the fastened state, the head 10a of the bolt 10 is connected to the penetrating portion 9 of the elastic body 9.
Since the head 10a and the vibration ring 7 are disposed only in the inside a and are shifted in the axial direction, during operation,
Even if the vibration ring 7 swings widely in the rotational direction, the vibration ring 7 will not come into contact with the head 10a of the bolt 10. Therefore, even when a large amplitude vibration is input, a damping effect can be obtained, and the vibration ring 7 can be prevented from repeatedly coming into contact with the head 10a of the bolt 10 and loosening the bolt 10.

As described above, the torsional damper of the present invention is a vibration ring that is arranged in the axial direction relative to a hub, and a plate is attached to one end of the vibration ring via an elastic body.
The vibration ring and the elastic body are provided with through-holes for inserting bolts, and the plate is bolted to the hub, which allows the plate to be made smaller and its shape simplified compared to the conventional technology. Also, since no mounting space is required on the inner circumference of the hub, assembly is possible even when such space cannot be secured, providing a compact and highly practical product.
In addition, because the bolt head is positioned only within the penetration portion of the elastic body in the fastened state and the head and the vibration ring are positioned offset in the axial direction, the vibration ring will not come into contact with the bolt head even if it swings widely in the rotational direction during operation. Therefore, a damping effect can be obtained even when vibrations with large amplitude are input, and the bolt can be prevented from loosening due to the vibration ring repeatedly coming into contact with the bolt head.
